Natural decor is always in trend! To make these cool coasters you’ll need slices of birch wood, polyurethane spray, metallic acrylic paint, paper towels and a stir stick. First, you’ll want to mix up your paint. Mix a ratio of equal parts of paint and water. You want the paint to be diluted when you use it. Once you have everything mixed, dip your folded up paper towels into the water. You’ll be using them as your “paintbrush” for this project. Begin “painting” the tops of your birch wood slices. The paint will not completely coat the wood, and that’s what you want! You should still be able to see the wood grain easily through the paint. Keep reading the tutorial in the source.
